In non-hydroxylic solvents a mixture of a-and (3-oxophosphonium salts and triphenylphosphine dibromide was formed in the reaction between triphenylphosphine and 2-bromocyclohexanone, probabty by initial attack on bromine. The proton nmr spectrum of the dissolved salts showed the presence of a vinylic proton attributed to the quasi- phosphonium salt. The reaction is very strongly catalysed by alcohols and water, under ...
